WINDOW VENTILATOR.

Application filed October 21, 1924i. Serial No. 744,884.

V1li window ventilator; Fig. 3 is a horizontal section taken along the plane of the line 3-3 of Fi 2 looking in the direction of the arrows; ig. 4 is a vertical section taken throu h the upper portion of one of the 20 side games and through the sliding shoe which is mounted therein, and Fig. 5 is aI sectional view taken along the plane of the line 5-5 of Fig. 2.

. Like reference characters indicate like 25,parts throughout the drawings.

Referring to the drawings, indicates generally the upper portion of the window frame within which the swinging window ventilator is mounted, this portion of the frame in the form illustrated comprisinga T-bar 11, the ange 12 of which is located on the outside of the wall and the rib 13 of which extends toward the inner portion of the wall. The upper portion of the frame also comprises a bar 14 irregular in cross section, as indicated in F'g. 1, and 'provided with flanges 15 and 16, r spectively, extending toward the window ventilator and forming seats :for the upper portion of the sash of the window. The side frame (see Fig. 5) in the form shown, also comprises a `Tbar 17 against which is secured a deep channel bar 18, the ends of which are engaged by the sash for the ventilator at the side of the window, as illustrated in Fig. 5.

' In the form shown, the upper portion of the sash of the window ventilator is formed of a bar 20 Z-shaped in cross section, as illustrated in Fig. 1, while the sides and bottom of the sash are formed of T-shaped members 21-22, respectively,I see Figs. 5

and 1). The ventilator is pre erably piv-- otally mounted at 23 on the upperzends of two swinging' arms 24 at opposite sides of the ventilator. Only one of the arms is illustrated at one side of the ventilator, it being understood that the opposite side of the ventilator is or may be formed the same as the side that is shown. The swinging arm 24, in the form shown, is pivoted at its lower end at 25 on a yoke-shaped bracket 26, the base of which may be secured to the side fralnecof the windows by bolts as at 27. In the closed position of the window ventilator the sash frameengages the window frame to form substantially tight joints, as indicated in Figs. 1 and 5. When the ventilator is moved to the open position, indicated in dotted lines in Fig. 1, the upper end of the arm 24swings outwardly, the lower part of the window swinging outwardly, while the upper portion thereof moves downwardly to the dotted line position indicated in Fig. 1.

In accordance with my invention, I provide means for readily and eifectively retaining the ventilator in any position to Lwhich it maybe desired to adjust the same.

In the form shown guide members 28-on the side portions of the frame, and only one of which is shown in the drawings, are provided with a vertically extending slot preferably on the intermediate portion of the inside wall, as at 29 and as indicated in Fig. 3. The guide member is suitably secured in the side frame in any desired manner. The guide member 28 is preferably formed of non-corrosive material such .as bronze, brass or copper which is not substantially affected by atmospheric conditions. 'Within the guide member 28 is mounted a sliding block or shoe 30, on one side otwhich is secured an outwardly bowed spring 31, the ends of which are received in suitable notches 32 formed in the shoe 30. The fr spring rictionally engages one side wall of the tubular guide 28 and forces the shoe into frictional engagement with the opposite wall of the tube. In the form shown, an arm 33 is bolted or otherwise secured to the 10o top member 20 of the sash as b bolts 34, the outer end of the arm prefera ly being cir cular, as at 35, which is received in an opening 36 in the shoe or block 30. As the window is moved toward open position, the friction blocks or shoes 30 move downwardly in their guides, and the friction springs serve to retain the same in any positlon to which they are moved and thus served to more, by forming the guide '-member in n which the block or shoe is mounted tubular in form with only a slot at the inner side, which is closed by the side sash of the Window when in closed position, it is impossible for the painter to reach the interior of the tube and apply paint thereto.

The friction shoe provided with a spring of the form shown is exceedingly simple both in construction and operation and does not require adjustment from time to time.

I claim:

l. In combination, a Window frame, a metallic, unitary tubular guide, rectangular to press the shoe against the opposite side of the guide.

2. In combination, a Window frame, a metallic, unitary tubular guide, rectangular in cross-section and formed of non-corrosive metal and having a narrow slot'in its side, 40

a shoe slidably mounted in said guide, a, Ventilating Window swingingly mounted in the frame and provided With a pivot member extending through said slot and pivotally connected to said shoe and a sprin@r 4 member frictionally held on said shoean engaging a side of the guide parallel to the axis of said pivot and arranged to press the shoe against the opposite side ofthe ide.
